Dementia is generally diagnosed when cognitive decline (difficulty thinking, remembering and concentrating) becomes a daily handicap for the elderly person and those around them. Research sheds light on long-term effects of internet use on dementia risk.

For the elderly, regular Internet use is associated with half the risk of dementia than non-use of the computer network. This is suggested by a new study long-term study by researchers at New York University on 18,154 adults, with previous work looking only at short-term effects.
However, excessive Internet use (more than six hours a day) is proven to be detrimental to cognitive health. It is therefore a matter of finding a balance between non-use and excess; estimates of hours of daily use by study participants suggest a “U-shaped” relationship with the incidence of dementia. The lowest risk of dementia was observed in people who used the Internet between six minutes and two hours a day. ” But the estimates were not significant due to small sample sizes “, note the researchers.
A correlation to be specified
They followed adults aged 50-65 without dementia for up to 17 years (median: 7.9) in the Health and Retirement Study Health and Retirement Study. Gender, ethnicity and level of education did not influence the results one way or another.
It should be noted that, while the study shows a correlation between Internet use and cognitive health, it does not prove a causal link. Less frequent Internet use does not necessarily cause dementia, nor does going online guarantee prevention.
